It didn’t thrill me but it did pique interest. IMO going from land to sea was much easier (to be a nomad) then it was going from earth to space. Two vastly different means. So it’s a bit facetious and rhetorical to ask that question. Yes some of us would like to be nomads but that’s easier said than done

If you guys saw that tv show the boys in the opening episode you have the runner just PLOW through that woman on the side walk. It's a similar comparison. If you try to put 1 human through another human its bloody difficult. But add speed and you now have kinetic energy making you much more packed with mass and evenly focused and moving in one direction and boom he plowed right through her. Same thing with a ship. As long as you have a good heads up display to avoid bigger things like planets and comets I think you would plow through smaller objects in space due to your mass and speed. Kinetic energy is where its at. Throw a bullet through someone by hand. It's not going to do much. Now fire it from a gun and that lead piece will you right thru you.

Yeah this is a problem that realistically seems to be one of the biggest concerns for me. I know there is a huge open space with nearly nothing between stars (and galaxies) but an asteroid the size of 1 mm that hit us at near-lightspeed would basically have the impact of a nuclear bomb i think. How do you prevent that? Sure, we can think of some new exotic matter or shielding that could withstand the impacts but eventually you have to turn the ships antimatter engine around to decelerate and when you do that, wouldn't you have the risk of impact again? Maybe you could shield both front and backside - dunno. They touched this concept in the new Star Wars movie

Hello. Great video! Would love to help clarify for viewers: At 85% the speed of light, using antimatter propulsion, someone would arrive in 2.7 years, not 5. To us, of course, nothing can go faster than the speed of light.. which is a crazy thing considering that Alpha Centauri system is approximately 4.367 light years away. However, we have to consider relativity. On Earth, 'I see' (with my own eyes) that it takes 'you' 5 years to travel to Alpha Centauri. On the other hand, if 'you' are the one traveling to Alpha Centauri, only 2.7 years pass between the time you left Earth and arrived on Alpha Centauri. Gotta love time dilation.

@AndyChungsCarromPool

However, it makes me wonder and it makes me anxious just by thinking that a person who took off to Alpha Centauri would just feel as if 2.7 yrs have passed while it would be 5 years for us. The gap widens again with our target being distant. So does it mean that the person on the spaceship is a futurist who can actually go forward in time? I am not an astrophysicist just a novice but always curious and silly!

Seriously though.. if humans weren't so petty and we worked as a species instead of killing each other and dividing ourselves into nations and religions, we'd totally have a manned base on Mars by now.

Thanks for a very interesting, and even inspiring video! I think one thing that people don't take into account (and indeed, doesn't get mentioned often - even by professionals) is the simple and obvious fact that if (or when, as I prefer) we *_do_* make it to some other world with a living crew - whether that world is Proxima b or Mars - living conditions are not going to be favorable! We can only go there (again: wherever *_there_* is) expecting to either stay in orbit - using any available materials from asteroids, comets, etc. - to build larger orbiting platforms such as O'Neil cylinders, *_or_* we're going to have to build closed-off habitats down on the dirt, so to speak - either heavily shielded or domed structures above ground, or dug-in structures underground. Terraforming is *_not_* a light undertaking. If we go there for the long haul, we'll end up building a LOT of infrastructure before we even begin to consider it, as it could easily take millennia to accomplish (if it's even something we can do, really.) So I would deeply and greatly hope that *_all_* aspects of such a venture would be carefully considered - not piecemeal, by this company handling this, and that company dealing with that - but with *_all_* the companies, personnel, astronauts, etc., thinking through every bit of it, and considering every angle. To that end - and I know you may not think this is your 'area' - I truly believe the first long-term, if not permanent, colony we every build should be on the Moon. We've *_all_* got to get this right! The things we learn about living on other worlds - by living on the Moon first - will be nothing less than critical for the future of space travel - at *_any_* speed, and to *_any_* location.

Yeah makes no sense.... If its possible to bend Time and Space and travel somewhere else instantly then time shouldnt move at the Solar System... That ship should be able to back and forth using the same amount of time...

1) Like in the book "Tau Zero", you are forgetting that you need to flip around and start decelerating half-way to your final destination or you will simply fly past it very fast. This will probably increase travel time at least 2x and probably 10x (I believe time dilation is exponential). You will probably need some sort of actual shields to protect you from space dust and such in the direction of travel. 2) I believe the best "propulsion" comes from the "Philadelphia Experiment" and "Montauk Project". This is matter/people teleportation. I think I read somewhere that it is actually being used now to place people on the Moon and even Mars almost instantaneously. A ship like this can probably get to Alpha Centauri in days in several hops. In fact, I believe, we have already colonized planets around stars to at least 1000 LY WITHOUT time dilation. Look into it...

I think we will learn to compress space in front of a craft and expand space behind a craft and go much faster than light speed .

So a few questions I have about his time/distance numbers: 1) Is he accounting for deceleration? Or just a constant acceleration? Like would the burn be going the whole way or would they flip at halfway or so to begin deceleration? Would it have to be at the halfway point to accommodate the 1g limit? 2) If we're deciding to send people - what about a return journey? 3) Why not just send robots? Wouldn't they have much higher limits on acceptable gravity, what with no squishy bodies and all?

An interesting sci fi idea would be: an exploratory vessel was sent out 1,500 years ago to Kepler B. Now it's coming back. Follow the struggles of the crew reintegrating, and the people on Earth in adjusting to what they brought back. Because they met aliens. They shared some technology. But in the meantime, Earth has progressed as well. So now Earth is, say, beyond the concepts of monogamy and gender and sexuality, so it's like the crew are from the 1860's coming back to the 2010's. But they have technology Earth doesn't have, and can create a post-scarcity society. Maybe also throw in there's no such thing as privacy anymore and does the crew want to hand the technology over to an invasive corporate government? Lots of ways to take it.

That is a theory based on some highly debatable proof. If you take a close look at the proof then you'll see some holes appearing. There is a part of the scientific community that thinks that it isn't expanding or at least not as fast as they think.

Great argument Why explore space? Because that’s what we do Maybe we should prioritise differently

Exploration is one of life's purpose, it shall be done synergistically while helping people in need here on earth (for example build housing for poor people living in extreme environments, hot or cold, to help perfect housing designs for other planet). To travel light speed we will have to travel as informations in a laser beam which can trigger matter in an other planet to form nanobots which in turn form robots. The next step is then to upload ourselves as informations into them. AI will be us uploading ourselves into avatar robots (transcendance). As for spacetime, I understand it as the perception of it to be relative. Time is based on the rotation of planets, so travelling light speed won't change planetary movements but change our perception of time on earth, which will come back to normal during the return trip.

It is amazing that Elijah Wood found time to focus on space travel after his acting career

Given the chance, I would definitely embark on something like that, it’s a once in a lifetime opportunity, imagine that, being among the first humans in another system, galaxy.. if many worlds are conquered over a timespan, one day humans can become the first (maybe) sentient beings connected by multiple interstellar - planetary communities.

I really appreciate the work that you guys are doing, and I understand that when you discussed the time needed to travel to the edge of the observable universe, you just wanted to qualitatively illustrate the vast distances possible to travel at an acceleration of 1 g. But it is actually impossible for us to travel to the edge of the universe even at the speed of light because the universe is expanding at a greater speed because of the presence of dark energy. Just wanted to clarify this so that people do not develop wrong perceptions.

Why does no one ever bring up the fact that it does not matter how fast you travel, you can't travel in a straight line..... eventually you would hit a planet or debris.

If you try Bussard ramjet (collecting atoms for hydrogen fusion) you slow down more than accelerate. i.e. no way you can collect needed atoms, perhaps onboard turn them to antimatter etc. on the way - you should still carry the mass like ordinary rockets do OR get stream of propellant somehow from somewhere for a very long time. Energy of this received propellant would diminish as the ship would get closer to lightspeed. Not to mention all stuff the ship'd hit... This guy is a fraud. He could've as well counted how many kg's of food needs to be stored for 50 years voyage ignoring all other problems !

It's also not possible to reach high relativistic velocities, even with an anti-matter photon drives (which this researcher does not propose, he proposes conversion to charged particles first). You'd be lucky to get to 10% to 15% c with this engine. Which is pretty damn respectable. You'd be tooting around the solar system very nicely at those speeds. As long as you don't hit anything. But interstellar with that technology would require suspended animation or life extension.

Why should we explore space? Because it’s f*cking AWESOME!!!

Very interesting talk, I enjoyed watching this video.

Interstellar travel might occur without intentionally trying to do so. Primitive man migrated to six of the seven continents on Earth not be intentionally traveling to another continent but by building another village over the next hill. Likewise, if we just build Stanford Torus's, Bernal Sphere's and O'Neill Cylinders out of asteroids and comets then we would migrate to nearby stars without even trying to do so. There would be no issue of being outpaced by faster technology as the habitats you live on would be your destination in the first place and we already know there are interstellar resources as an extrasolar asteroid recently passed through our solar system. One asteroid can build and power a lot of city scale habitats.

So I guess the Star Trek idea is off the table, if you want to boldly go where no one has gone before, it would mean never coming back. Or is anti-matter just not the way to go? Space folding? Artificial wormholes? Instantaneous travel from one point in space to another seems the only way to have interstellar travel and be able to do it without time debts. As a trekkie I'm a bit disappointed.

Technically, laser propulsion of light sails could easily out accelerate an antimatter drive so long as the light sail could still be targeted by the laser which brings to mind the concept of laser relay stations to establish a highway in space. Remember reflecting light doubles the momentum you receive and with sails you do not have to carry the energy source not the propellent mass.

Callum Macleod he didn’t say faster than light he said faster than light sails a light sail travels at 20% the speed of light. Also things can travel faster than the speed of light.

Julio Giron nothing can travel faster than the speed of light in a vacuum but the universe itself is expanding faster than the speed of light causing everything within the universe to slowly accelerate to infinite speeds, everything on the outer edge of the universe is expanding faster than the speed of light so we can never see it again because the objects themselves are traveling too fast for the light to catch up to us

We should differentiate interstellar travel and crewed interstellar travel. Right now, we're capable of the former; we have several interstellar missions(i.e. space probes) already on their (slow) way. The more recent ones actually contain info making them a real mission, with info on us, etc. As to crewed such efforts, we might put a crew in suspended animation(not possible at this time), make it a generational ship, or use tech close to 'magic'. One concept was in Dune, i.e. 'folding space', or interdimensional travel.

When I was 14 years old in the year 2000, I posed a question to a guy giving a speech at a local university about 3D printing. Now, that vision has come true. As such, I believe that we will one day build teleportation devices for living beings, food, etc which will (on a basic level) be 3D printers.

We have to start moving at light speed to interstellar travel. So get materials to harness the sun's power from other planets, bring it back and build a space ship like ship. Or an element that uses/manipulates the force of gravity as energy, positive or negative. Gravity is everywhere in space. Travelling to another Galaxy would need a time machine , which in science isn't so far fetched if you can harness the power of a blackhole.

Even if we have anti-matter propellant, how to maintain 1G acceleration when the spaceship's speed reaches near light speed? Wouldn't it take almost infinite amount of energy?

This is an excellent lecture. The space race should be about speed, not about seeing who gets to put the first man on Mars. The development of Space travel and the development of AI computers go hand in hand. A superintelligent computer will figure out how to make interstellar travel possible and it will lead us there. So, money spent on the development of AI computers is actually an investment in future Space travel. The research in antimatter rocketry provides the basis from which Ai will build upon.

I do believe that our dreams will come true. We look at the stars and hope to reach them so our best minds which have ever lived and live now have worked together to build hopefully a future for mankind in interstellar space. Sadly we will not be around to see it.

Very nice ending, makes me dream!

So, if we send someone on a near light travel to another star... won't we beat them to it? To them it would take years... but to us, we would have enough time to figure out faster then light travel and get there before they ever do.

supergps2000 did you watch this video? Someone traveling 80 percent the speed of light with current technology will take just under a decade to reach our nearest star. People on earth would observe those travelers as taking 150 years to get there. The travelers will experience time around them speed up while they remain un-effected. They will personally experience 8 years of time while everything 80 percent the speed of light slower then them experience 150 years. They will get to there destination 150 years later but would only experience 8 of those years. They are traveling through space so fast that they also travel through time at an accelerated rate, hints Time Space. Idk how else to explain it. We have 150 years here on earth to beat them there by learning to bend time space and get there in just days without experiencing that same time dilation. Hell, they might be arriving to a future human settlement.

Imagine millions years later, all good planets in Milky Way colonized by humans without any space bending stuff. Тraveling faster than light impossible, thus there won't be any interstellar community, All colonies will on their own like separate civilizations with own history and culture. They will only receive messages from other colonies sent. hundreds or thousands years before. And eventually they will forget what planet humans came from or maybe some civilizations will not.
